2 Office of Electricity The Office of Electricity Delivery and Energy Reliability (OE) drives electric grid modernization and resiliency in the energy infrastructure. OE leads the Department of Energy s efforts to ensure a resilient, reliable, and flexible electricity system. OE serves as the Energy Sector DOE Specific Microgrid lead for the Program Federal India emergency Smart response Grid Forum when activated by DHS/FEMA. Technology Innovation Grid Modernization Security & Resilience Institutional Support & Alignment 2

3 Microgrid Program Vision Vision The Integrated Microgrid Program foresees the technical requirements for advancing the microgrid to a fully integrated entity within the distribution system, interacting seamlessly with the Distribution System Operator. India Smart Grid Forum 3

4 Where We Are Where We Are Going Workshops Microgrid Controller / DMS Simulations Collaborations Use Cases IEEE Standards DMS Field Demonstrations Microgrid Controller Metrics and Testing Regulatory Reform PAST PRESENT FUTURE

5 Advanced Microgrid Concept India Smart Grid Forum Advanced Microgrid Objectives Operational modes System architecture Technical challenges Development impacts Ownership Microgrid applications Standards and codes Controllers References An advanced microgrid is one that provides functions at the PCC beyond basic islanding (disconnect) and synchronization (reconnection) functions. An Advanced Microgrid interacts with the larger grid (macrogrid) cooperatively managing power flows across the PCC optimizing benefits for both the microgrid and macrogrid. 5

9 Hardware in the Loop (HIL) Testing Digital real-time simulation allows researchers to study multiple scenarios in near real conditions and without risk. They can integrate a power amplifier to introduce more realism and perform tests using real power flow between the simulated environment and real hardware. This is known as Power-Hardware-In-the-Loop (PHIL) simulation. Purpose Provide standardized and independent testing Reduce deployment cost for new devices and solutions Perform research Investigate safety issues Facilitate standards development Conduct testing of: Both system level and device level India Smart Grid Forum Microgrid energy management Microgrid control and operation Communication Protection 9
